Lets say we have x sheets in the newspaper. We know that one sheet can provide 4 pages in a newspaper.

So if we have x sheets we have 4x page numbers.

Now when numbering outerside of a sheet get page numbers like 1,3,5 etc(odd numbers). So they are before the middle page. After middle page the outer side gets even numbers. you know the last page number is 4x which is a even number. So after the middle page we have even numbers in outer side o the sheet.

So before middle page inner sheets will have even numbers and after middle page they will have odd numbers.

Consider the first sheet.

we have page number 1 in outer side bofore middle. After middle the same sheet will have page number 4x which is the last page.

now please see the two points which i showed below. In the left point i show the page number before middle and in the right corresponding page number after middle is shown.

(1,4x)

(2,4x-1)

(3,4x-2)

(4,4x-3)

(5,4x-4)

(6,4x-5)

It is given here that we have a page number 27. So middle page is far away than page number 6. since it is even it is a inner side page of the sheet. So outerside will be page number 5. In the same manner 27 is page number which come after middle page. so opposite will be 26.

 

consider (6,4x-5) point. It is given that 4x-5 is 27.

4x-5 =27

   4x = 32

So the number of pages in the newspaper is 32.

 

Note:

Actually there is no middle page in a newspaper. I used that expression because it is easy to understant by that.
